We can keep this simple. According to the Gospel of John, Jesus was God incarnate. In John 17, Jesus prayed that his current and future followers would have the kind of unity that he and his heavenly father enjoyed. He requested this so that the world would have a basis to believe that God had sent him.

“I do not ask on behalf of these alone, but for those also who believe in Me through their word; that they may all be one; even as You, Father, are in Me and I in You, that they also may be in Us, so that the world may believe that You sent Me.” John 17:20-21 (NASB)

That was the prayer.What kind of results did the self-proclaimed Son of God get?
It’s 2013.

Christianity is divided into Catholic, Protestant, and Orthodox, and their Bibles differ in what books are included in the canon of Scripture. Protestants disagree over which is the most accurate English translation to use. According to the Pew Forum on Religion & Public Life report in 2011, there are over 41,000 Christian denominations and movements. Even within particular denominations, there is infighting, controversy and schism.

The passage of time only reveals an increasingly fractured Christianity.

What conclusions can we draw from this?

The prayer for unity by Jesus was a resounding failure, and there is no reason to believe he was sent by God.
Perhaps the prayer attributed to him was a pious fiction, or maybe he was a false messiah rejected by a real god. Most likely, there was no god to hear his prayer.

Why should anyone waste time praying in the name of Jesus, when the Bible and history reveal that one of the most important prayers Jesus supposedly uttered went unanswered?

Perhaps this is a good question to ask our Christian friends: If Jesus was God, what use is a god who cannot answer his own prayer?
